Gas mask type respiratory protection equipment. The protection of the respiratory tract is achieved by filtering the outside air by means of a specific filter for sublimation oxalic acid.
The mask is designed to isolate the airways and the view of the operator by means of the adequate tightness with his face against an atmosphere with the presence of gases, vapors, liquid or solid particles or microorganisms in suspension. The Vistro 300A2P3 filter is not included with the mask. The filter mounts to the front of the mask.

Note:The user of the mask or mask must not have a beard, as the hair interferes between the mask and the user's skin, preventing a good seal. This lack of tightness can cause contaminated air to leak into the mask without passing through the filter, thus reducing its effectiveness.
